<i>Egretta caerulea</i> Length: 24" <p> Little Blue Herons are a small heron and are uncommon in the Bay Area. I have only seen them while visiting the south. There was one reported in Fremont, CA for a couple of summers, but I was not lucky enough to spot it. </p> <p> Little Blue Heron's eat fish, frogs, crustaceans, and small rodents and insects. </p>
